[Study of the transversal repartition of the electrical field of paroxysmal discharges in petite mal epilepsies (author's transl)].
A precise analysis of the topography of the EEG critical discharges of Petit Mal, permits a description of two principal varieties, depending whether their electrical field presents two lateral and symmetrical peaks--usually on frontal areas--('lateral variety') or one peak on the mediosagittal line ('medial variety') of the scalp. The relationship which exists between the lateral distribution of EEG discharges and the 'simple' aspect of the absences, on the one hand, and the medial distribution with the 'complex' aspect, on the other, is so close that one is led to hypothesize two distinct epileptogenic processes.
